前段时间写的一个Tweak,用来保存友秘(
2deK9s2c8@1M7q4)9K6b7g2)9J5c8W2)9J5c8Y4N6%4N6#2)9J5k6i4N6#2L8h3W2A6i4K6u0W2j5$3!0E0i4K6u0r3i4K6t1&6i4@1f1%4i4K6W2m8i4K6R3@1i4@1f1#2i4K6S2p5i4@1t1K6i4@1f1#2i4@1t1H3i4K6R3$3i4@1f1&6i4K6V1@1i4K6R3H3i4@1f1$3i4@1q4r3i4K6R3I4i4@1f1%4i4K6W2m8i4K6R3@1i4@1f1#2i4K6W2n7i4@1u0q4i4@1f1%4i4K6R3&6i4K6R3%4i4K6u0W2
功能如下:
1. 友秘默认查看图片只有2秒后销毁,使用该Tweak后,延长到20秒.
2. 图片销毁时,会弹出一个对话框,问是否保存该图片,选择保存,会保存到相册中.
